Erik Brynjolfsson (born 1962) is an American academic, and Schussel Family Professor of Management at the MIT Sloan School of Management, the Director of the MIT Initiative on the Digital Economy, Director of the MIT Center for Digital Business and a Research Associate at the National Bureau of Economic Research, known for his contributions to the world of IT Productivity research and work on the economics of information more generally.
Brynjolfsson earned his A.B., Magna cum laude in 1984, and MS in Applied Mathematics and Decision Sciences at Harvard University in 1984. He received a Ph.D. in Managerial Economics in 1991 from the MIT Sloan School of Management.
Brynjolfsson has served on the faculties of MIT since 1986, Harvard from 1985 to 1995 and Stanford from 1996 to 1998. In 2001 he was appointed the Schussel Family Professor of Management at the MIT Sloan School of Management. He lectures and consults worldwide, and serves on corporate boards. He teaches the popular course 15.567, The Economics of Information: Strategy, Structure, and Pricing, at MIT  and hosts a related blog Economics of Information. He was also a contributing member to the Winter, 2004 Boston Ski and Sports Club (BSSC) Championship flag football team.
His research has been recognized with nine "best paper" awards by fellow academics, including the John DC Little Award for the best paper in Marketing Science. Brynjolfsson is the founder of two companies and has been awarded five U.S. patents. Along with Andrew McAfee, he was awarded the top prize in the Digital Thinkers category at the Thinkers 50 Gala on November 9, 2015. 
Brynjolfsson is of Icelandic descent.
Brynjolfsson's research interests focus on the economic impacts of information technology on productivity at both the level of the firm and the economy. He has examined a number of topics like intangible assets, information worker productivity, the Long Tail in digital goods, and business process replication.
More recently, in his books The Second Machine Age and Race Against the Machine, Brynjolfsson and his co-author Andrew McAfee have argued that technology is racing ahead, and called for greater efforts to update our skills, organizations and institutions more rapidly.
Information Technology and Productivity
Brynjolfsson wrote an influential review of the "IT Productivity Paradox" and in separate research, documented a clear correlation between IT investment and productivity. His work provides evidence that the use of Information Technology is mostly likely to increase productivity when it is combined with complementary business processes and human capital.
